In this scientific article was studied the main methods for assessing the seismic effect generated during the blasting operations with explosives, from quarries on essential infrastructure elements, in the analyzed situation - railway tunnel and supporting pillars of the railway superstructure in the adjacent area of the quarry, regarding the most appropriate technique for estimating and assessing the seismic effect through the specificity of the evaluated parameter.  In order to be able to carry out an activity with as little impact as possible on the environment, the economic operator carrying out career blasting works must apply technical measures to ensure the protection of civil / industrial objectives in the area close to carrying out these works.  The establishment of measures leading to the maintenance of the stability and integrity of the objectives, as well as to the protection of the environment, is based on an artificial earthquake assessment process, which highlights the possible effects on the adjacent area.  The evaluation of the seismic effect can be done by monitoring some parameters that characterize the seismic waves produced by quarry blasting such as: frequency of oscillations, amplitude of movement, soil particles oscillations velocity, acceleration of oscillations, duration of their manifestation.
